摘　　要：目的评价玻璃离子粘固剂联合银汞合金双层充填法治疗龈壁过浅龋洞的临床效果。方法对74例患者的78颗龈壁过浅的龋洞随机采用双层充填法或银汞合金单独充填法进行充填,1年后比较充填成功率。结果双层充填法的充填成功率为87.23%,高于银汞合金单独充填法(61.29%),有统计学意义(P<0.01)。磨牙龋洞的总充填成功率为78.79%,稍高于前磨牙龋洞的75.56%,差异无统计学意义。结论应用玻璃离子粘固剂联合银汞合金双层充填法可显著提高龈壁过浅龋洞的充填成功率。Objective To evaluate the clinical effects of treating proximal cavities which have a shallow gingival wall by filling them with glass-ionomer cement and silver amalgam （double filling method）. Methods 78 proximal cavities from 74 patients that have a shallow gingival wall were filled randomly by double filling method or silver amalgam alone. The success rates of filling were compared one year later. Results Compared with the silver amalgam alone method, the double filling method significantly improved the success rate of filling （87.23% vs. 61.29% , P 〈 0.01 ）. The total success rate of filling molar cavities was slightly higher than that of filling bicuspid cavities （78.79% vs. 75.56% ） , with no statistical significance. Conclusions The double filling method can significantly improve the success rate of filling the proximal cavities which have a shallow gingival wall.
